I like your fledgling story and photos.
I remember years back when I lived in an apartment, a bird had made a nest on my balcony on top of a post. I knew they were there, but one day I heard the most tweeting and tweeting and I went to the back door window and looked out. There was a baby on the ledge and two on the balcony floor and the mother had flown back and forth from the balcony to the trees behind the building a few times and was calling to them. I stood and watched for the longest time as the babies began to get the message and one by one, flew up into the trees with their Mom... and then they were gone and all was silent. That was pretty neat to watch.
Birds are really fascinating to me to watch. I don't understand all the behaviors but it is fun to think about why they do the things they do. They are generally pretty easy to get along with as neighbors unless a large group of vultures decides to move into your tree or something, lol.
I am semi rural, on the edge of what use to be a big farm and so there is lots of bird activity. There are several hawks, a few large and a few smaller ones and when they are near, everybody else scatters ! Sometimes one sits on my back fence, facing the field and sometimes I see a large one sitting on the fence across the front road at the edge of the horse pasture. So far, I have never actually witnessed one take another bird or rodent down, but there is a bunny that lives under the bushes at my back fence and one day it "appeared" to be a mature hawk and a young hawk and I thought the older one was trying to show the young one the ropes. They were camping out in some trees beside my yard and I was just sure "bunny" was going to be their lunch, but a few weeks later, I saw bunny again and was kind of happy that it had not been a victim.
There are a lot of hawks and eagles around here. I've seen the results of their hunting a few times. Once a big eagle (or maybe large hawk?) got a rat from the backyard. I was really surprised to see it sitting on the backyard furniture, I did not think it was a clear enough area for a bird that large to get in and out easily.
